I believe the fiber optic input on the Onkyo TX-DS575 is shot. Fiber optic cable is transmitting fine from DVD player and all other input options work fine. How do I get my hands on a replacement part for the fiber optic input?

Fiber Obtics is activated all the time on most units. take a look at the fiber connector, if you push the little door on the connector and look in side you should see a fiber optic light glowing red. If not there is a problem with the units Digital.
1. Connect the digital input(optical) on the product to the Digital output of the external digital componet.
2. Press the FUNCTION button to select D.IN input.
* The mode switches as follows: BD/DVD -D.IN-ONLINE-HDMI 1-HDMI-2-FM.
HD Video FROM your TV???? Video goes TO the TV and gets there either via direct tuning of an HD air station or from a Cable?SAT box, BluRay player... The unidentified TV's manual should cover that.
The Onkyo's manual covers most of the rest.
NO signal ever benefits from multiple connections or 'hops' and it gets expensive zig-zagging a signal all over the room. K-I-S-S is the word of the day. Run the BEST version of any signal directly from its source to the BEST electronics that will present it to you for consumption. The separation of audio and video inputs and outputs on a device is what allows and ENCOURAGES the routing of each signal to the BEST electronics that can process it. Example: your TV does not have the best speakers in the room so why send it any high-end audio?
If the sound actually comes from an external source treat that source like any other hi-end audio component and attach its highest quality audio directly to the receiver according to ITS manual. The separation of audio and video inputs and outputs on a device is what allows and encourages the direction of each signal to the BEST electronics that can process it.
As far as the TV audio goes... unless it is the primary source of the audio (tuned through its own antenna and available no where else) why don't you just run the actual primary source's (cable/sat, whatever) best digital audio straight to the Onkyo and skip the middleman that adds nothing to it but expensive unnecessary cable hops.
I'd also run each video sources absolute best video straight to the TV for the same reason.
Hi troy my names Josh i would be glad to be able to help you with your setup. First things first some people have a preference with they way they like things and for one do myself. I set up and intstalled my home theatre. I have receiver much like yours. On the back of your reciever you should have multiple inputs of coarse some for sound some for video. Your sound inputs would include digital optical, digital coax, standard analog which of coarse is the red and white RCA inputs and then a multi in which i doubt you have. So lets start simple If you have satalite or some form of cable i would assume you have your reciever box feeding a signal to your tv and the same for your DVD. I would recommend for your sat. that you connect your picture and sound strait to the tv rather it be component video or s video or standard video source or connect then for your sound strait analog to your tv thats just Red and White RCAs which will give you your sound to your tv. Repeat the same for your DVD depending on the kind of inputs and number of inputs you have on your TV. Now for the sound to your reciever. I ran digital sound from both my DVD and my Satilite to the reciever which means on the back of your recievers providing you have a similar configuration you would look for a plug on your dvd player that says optical thats your digital to run sound to your onkyo and the same for your sat or cable if you have a box look for either digital optical or a single digtal coax output that will also be ran to the onkyo for sound. You should only have two cables running to the onkyo one fiber optic from your dvd to the onkyo and one digital coax or fiber optic to your onkyo depending on the number of those inputs you have on the back of the onkyo you can run it how ever you want.
Receivers of this complexity require some patience. I believe the HDMI on this receiver is only for on screen display and video pass through. The audio needs to be separately connected. For digital audio you need to connect either via the digital audio coax or fiber optic input. I replaced my entire 1980s audio system with this unit and have been very happy. It's compact, and I feed it everything via a 35' fiber optic cable (under $20!) tied to a 3-way passive fiber switch (under $10) connected to my computer, a Tivo, and a DVD player. Sounds amazing (make sure to run set up to get the unit to perform with all of your speakers! -- I use an 8 speaker 7.1 surround set up).
Please determine if the "Audio" button is actually working.... after pressing the audio button, can you still control the DVD, if not then the remote has switched to the Onkyo. Although, this is not 100% conclusive, unless you have a 2nd remote to test the Onkyo with, it provides a sound basis to proceed.
Assuming the remote is transmitting and the IR receiver on the front of the Onkyo is not otherwise blocked, likely faults include the IR receiver, input to the Micro processor, and the Micro processor.
The most probable fault is the IR receiver.
Thank you for using Fixya, and if I can help you further, please let me know.
Check the settings on your cable box for "Audio" settings and check the output. Should be set to "Dolby Digital" If you need more help, post a comment with the make and model of your cable box and I can walk you thru setup. Hope this helps
Make sure your DVD setting is looking at the right audio inputs. Usually there is a menu option or a button to toggle from analog or digital input. Usually when no-sound but video ok, you have the wrong input-type selected. If you are using 2 RCS's (red/white) then you want ANALOG input mode. If you are usung a single RCA (orange) or a fiber optic input for audio, you want DIGITAL input selected. If digital os selected, make sure you plug into the correct digital input to hear. If it does not work at first, mofe the jack/fiber around into the different inputs untill you hear sound, then you will know which port is associated with the DVD setting. Unless it is self evident feom the menu.
